I rather liked that solution to fighting the Borg, actually. On Star Trek: Voyager they would have just beamed over a photon torpedo, detonated it, and called it a day. In "Descent" it took careful risk-taking to defeat what was still a powerful adversary -- even without the Collective mind.
But what I'm getting at is that if Voyager had done a similar situation wherein they spent most of the episode pissing their pants at the sight of a weakling Probe ship before they lured it near a Star and then caused a solar flare that destroyed the weakling Probe ship while praying to God that it would work, and then fly off a collective bunch of nervous wrecks that they overcame a weakling Probe ship...
...The audience would still say they had weakened the Borg, even if the writers went out of their way to portray the crew as being utterly terrified (and therefore, less competent than the Enterprise crew who showed apprehension but no fear).
Because a weakling Probe ship is more powerful than a Star. Just like the idea of there being even one species out there more powerful than the Borg is utter heresy.
